SETTLlN No. 845,520. Specification of satanic.

Letters Patent. Patented Feb. 26, i907.

Application filed November 27,1905. Renewed January 22, 1907. Serial No.353,525

.To (tl/f whom it 'may concern.;

Be it known that I, JOHN M. CALLow, a subject ol the King of GreatBritain, residing at Salt Lake City, in the county ot Salt Lake andState of Utah, have invented new and useful Improvements inSettling-Tanks, ot which the following is a specification.

ln settling-tanks used in treating the slinies ol ores it is of greatimportance that the ineans employed for drawing oil the values shouldnot only ell'eet that withdrawal coinl pletely, but should do it withoutagitating the mass in the tank. lt should also include nieans forflushing and cleansing the vents and ducts connected therewith. Thesefunctions require an accurate .adjustment of the inlets and outliows andcareful calculations as to the pressures andcther intermediate and iinaleltccts involved.

rlhis device is siphonic and comprises, essentially, a direct downwardchannel whose vertical axis alines with that of the settling! tank. Inthis channel is located a threeway valve. which' will permit a directilow through it or will cut oI'l' the llow and letin a current 'from alateral pressure-pipe, which may be directed upward or dmvnward, asdesired. v

@ther features of' this device will be explained in the descriptionjfollowing.

The drawings herewith illustrate theinvention, its` various 'featuresbeing referred In the drawings, Figure l'is a vertical section ot thedevice attached to'the lower part of tunneldorin settling-tank, thelatter being shown liragnientarily. Fig. 2 is a vertical section takenat a right angle to that of F ig. 1. Fig. 3 is a side elevation, partlyin section, showing a niodiiication ot the device.

The letter A (,lesignates a funnel-.torni settling-tan k having anoutlet a at its lower end.

lBv is a casting attached to the lower end of the tank A and serving asan exit therefor. This casting has a vertical channel b opening into thetank, its axis being in line with the axis of the tank, and a lateralchannel g2 continno'us with said channel b and extending on into a pipeH.

C is a valve-chamber formed by enlarging i the channel either in thecasting B or the pipe ll. This valve-chamber has a lateral opening c,provided with a cap e.

l) indicates -a thrceway valve located in the chamber C and havingocnings (Z, d?, and d3. d is a stein on said va ve connecting with alever c, by means of which the valve may be turned to control the flowAfronrthe tank or from a pressure-pipe I, having a channel i, whichconnects with the lnain channel through a core et in the chamber C.

f is a stopper for the opening b of the channel b.

G is a lateral extension of the casting hav ing'the channel g2.

J is a flexible hose connecting with the pipe H and provided with thenozzle j.

In the operative adjustment of the device shown in Big. 1 the iiow ofthe settled Inaterial is down through the valve D and by way of thelateral channel g2 and pipe H out through the hose and nozzle; but if bythe accidental introduction of foreign matter into the tank anobstruction gradually accumulates within the casting B or the pipe H orhose J and the free discharge of settlings Y ceases, by operating thevalve D water'under a high pressure can be intro duced for the purposeof removing and ejccting such obstructions. Should any obstruction occurbeyond the valve D, by a partial revolution of the valve the connectionto thetank is cut oil', and high-pressure water through t forces its waythrough the channels b and g and out through the nozzle. Should theobstruction occur in the throat of the casting, a simple reversal of thevalve-lever shuts olifthe conl' ncction beyond the valve, and the fullpressureV of water is brought to bear ori-the 0bstruction-here and tobrealit rip. Then by bringing back the valve to its'iirst position andremoving the stopperthe pressure ofthe v water in the tank above andgravity will together expel it through the passage b.

What l claim, and desire to secure, is-

1. In a settling device, a tank provided` with a discharge-opening, anexit-casting attached to the lower end of the tank and having a verticalchannel connecting with the opening in said tank, a connectlngpipe, saidpipe and the casting having a lateral outletpassage connecting with thevertical channel wthrough said casting, said discharge elements beingprovided with a valve-chamber, a three-Way valve. therein, means tooperate the same, and a pressure-pipe conneetin' through said valve withthe channel and wit thclateral outlet as described."r

2. In a settling-tank an exit-casting attached to the lower end ot saidtank, andvliaving a vertical channel connecting `.vitlif the opening insaid tank, a stopper for'the lower end of Said channel, said castinghaving u valve-Chamber, a three-way y'nhe in said ehainbermeans tooperate said valve, pressure pipe connecting with said channel lhroughsaid valve said casting having a interal outlet from said channel beiow.sa-id valve as described.

3. The combination with n funnei-for1n settling-tank having an openingat its lower ps1-rt, of @casting having :i vertical channel conneqfuingwith said openingand provided with a cvalve-chamber, a. three-wry Valvein said 'chamber, a pressure-pipe. connecting 'through said valve withsaid ehzmnoi, 'a stopi 5 per at the lower end of sind channel, a lateralout1et-pipe between said valve and the lower end of said channel, anupwardly-inclined y pipe connecting with said Aoutlet-pipe, and .aflexible hose on said inclined pipe for the purposes specified.

4. In zi`settling-tank, a bottom casting having e. veriezi-l and f1.lateral channel, a.

stopperfor Said Vertical channel, a pipe Conheating with sznd lateralchannel, :L threeway valve in sii-id pipe and a pressure-pipe Connectionwith sind valve, for the purpose specified.

in testimony whereof l affix my signature in presence oi' twosubscribing Witnesses.
